Discovered (Jul 24, 1835) by John Herschel
A 13th-magnitude lenticular galaxy (type S0) in Indus (RA 23 26 45.9, Dec -68 01 39)
The second IC notes "Group of stars, not a nebula (DeLisle Stewart)". Apparent size about 0.8 by 0.6 arcmin. |

Apparent size about 1.4 by 0.4 arcmin.
NGC 7658 (= PGC 71432)
Discovered (Sep 4, 1834) by John Herschel
A 14th-magnitude lenticular galaxy (type S0) in Grus (RA 23 26 24.9, Dec -39 13 37)
This is the southern of two very faint galaxies, separated by less than an arcmin (the other is listed below as "NGC 7658A"). Although both galaxies' magnitudes round off to the same 14th-magnitude value, this one is half a magnitude brighter and much easier to see, and since Herschel made no mention of a "double" nucleus or nebula, there is little doubt that he saw only this galaxy, and it should be listed as NGC 7658. However, some catalogs list it as NGC 7658B, as though its companion deserves pride of place, and as a result, Wikisky does the same. Apparent size about 0.8 by 0.3 arcmin. |

Discovered (Sep 5, 1828) by John Herschel

NGC 7661 (= PGC 71473)
Discovered (Nov 1, 1834) by John Herschel

NGC 7662, The Blue Snowball Nebula
Discovered (Oct 6, 1784) by William Herschel
An 8th-magnitude planetary nebula in Andromeda (RA 23 25 53.9, Dec +42 32 08)
Per Dreyer, NGC 7662 (= John Herschel's GC 4964, 1860 RA 23 19 11, NPD 48 14.0) is "a magnificent object, planetary or annular nebula, very bright, pretty small, round, blue". The second IC adds "The nucleus is variable to the extent of three magnitudes, with a period of 27 1/3 days (Barnard, M.N. lxviii. p. 465)".
NGC 7662 is 5 to 6 thousand light years away, and 50 to 60 thousand AUs across (its size being as uncertain as its distance). The central, bright portion of the nebula is about 0.6 arcmin across, but a fainter outer halo covers more than 2 arcmin. The nebula's central star is a relatively young, very hot white dwarf (about 75,000 Kelvins, or 135,000 Fahrenheit degrees). In small telescopes it appears to be a nearly starlike, slightly fuzzy 8th magnitude object. In a dark sky, 6 inch or larger telescopes reveal a slightly bluish gray ball (hence its name). The NOAO image below was taken with a 16-inch telescope equipped with a CCD camera. Its colors, though exaggerated, are more or less "true". The false-color HST images of the planetary nebula, aside from showing more detail within the nebula, reveal so-called "fliers", unusually dense outlying blobs of gas which were apparently ejected by the star before the formation of the central nebula.
